Oh, speaking of these functions...

When I do the nudge up or down, lines get pooted out to scrollback. If there is any way to nudge without that happening, it sure would be nice.

That sounds like a feature of the terminal emulator (or 'screen')
which lynx can't address.

But it doesn't happen when paging up/down, so what's different about lines?

As I understand your first comment, what is happening is that the curses (or whatever) library is updating the display by asking the terminal to scroll up/down by a few lines, then painting new text in the blank area.

For a pageup/down, it could be simply repainting the whole display -
if the whole screen changes, there's no point in shifting everything up/down to paint over it. (Even for a half-screen, that depends on how long the shifting is supposed to take, and whether the curses library notices this would be a good solution).
